silicaBerk | R Documentation |
Load and depth measured with Berkovich diamond tip on fused silica material.
Data contains only unloading part of indentation curve. The relationship between Load (F) and Depth (h) is given by equation
F = \alpha (h - h_p)^{m}
, where h_{p}
is permanent indentation depth after
removal of the load, \alpha
is fitting constant related to the indenter geometry and
power law exponent m should be from (1,2) interval.

The data frame contains two columns:
nanoindentation depth, in nanometers.
load, in milinewtons.
